How to Measure for a Box Liner

No matter what container or box size you’re working with, plastic liners will keep your products safe during transportation, storage, and processing. A-Pac manufactures custom-sized box liners in a variety of materials and thicknesses to suit your exact specifications.

If you’re wondering how to measure a box liner, follow the steps below. 

1. Determine the Length and Width of Your Liner

Length and width of liner = (length of box + 2) x (width of box + 2)

• • Example: The length of your box is 50 inches, and the width of your box is 42 inches. 
    • Length and width of liner = (50 + 2) x (42 + 2)
    • Length and width of liner = (52) x (44)

• The length of your liner will be 52

• The width of your liner will be 44

2. Determine the Height of Your Liner

Height of liner = height of box + width of box + 6

• • Example: The height of your box is 40 inches and the width of your box is 42 inches. 
    • Height of liner = 40 + 42 + 6
• The height of your liner will be 88

Note: The 6 comes from 6 inches of extra space you should give yourself for the tie-off section.

3. Finalize the Dimensions of Your Liner

The dimensions of your liner include: length x width x height

• According to the example above, your liner dimensions are: 52 inches x 44 inches x 88 inches

Measure More Packaging Materials

No matter what products you’re packaging, it’s always in your best interest to choose the right box liner, container, and bag size for your product. For example, the correct size poly bag will fit your products exactly, ensuring you’re not paying for more material than you need.
